Abstract: 

Telomerization of vinyl acetate (VAc) in chloroform and with 2,2’-azo isobutyronitrile (AIBN) initiator, was carried out to synthesize poly (vinyl acetate) (PVAc) with tri-chloromethyl (CCl3) end group which is called VAc telomer. The molecular structure and molecular weight distribution (MWD) of VAc telomers were characterized by 1H NMR spectroscopy and gel permeation chromatography (GPC). The effect of chloroform and AIBN on number average degree of polymerization (Dpn ) and percent of telomerization were investigated. The kinetics of telomerization was studied and chain transfer constant of chloroform was determined. The synthesized PVAc with CCl3 end group (VAc telomer) was used as macroinitiator in atom transfer radical polymerization (ATRP) of methyl acrylate (MA) with CuCl/2,2’- bipyridine catalyst system to synthesize novel block copolymers of VAc and MA. Molecular structure and MWD of the PVAc–b–PMA copolymers were characterized by 1H NMR spectroscopy and GPC.
